Abstract

Encryption method and system for iteratively, structurally converting a binary sequence into an encrypted final image. A selected transformation algorithm and an alphabet formed from the binary sequence to be converted is applied to an image of the sequence, and a resulting image is coded with an external key. Additional embodiments code portions of the image with extracted, and optionally scrambled, internal identifiers derived stochastically from the image being converted.
